SKATE}.

Specification of Letters Patent.

Patented. March 13, 1906.

Application filed February2 8, 1905. Serial No. 246,905.

to skates in use whereby in a skate in which both the toe-clamps and theheel-clamps are tightened by one lever the tightening of the toe-clam swillbe limited when sufficiently tightto old onto the sole of the shoebefore the lever reaches its home position and the rest of the grip willbe expended on the heel l vided with my improved clamp-contro forpreventing undue pinching of the ball of the foot when the resistance ofthe sole to the grip of the clamp is lessthan at the heel and it isliable to collapse and pinch the foot uncomfortably, as hereinafterdescribed, reference being made to'the accompanying drawings,

in which Figure 1 is a side elevation of a skate rofling attachment inone form of application. Fig. 1 is a detail in side elevation showing amodlfication. Fig. 2 is a plan view of part of the attachment as appliedinIFig. 1. Fig. 3 i'sa plan view of the sole plate and clamp invertedand showing a modified form of clampcontrolling attachment. Fig. 4 isanother plan view of the sole plate and clamp with another modificationof the clamp controlling attachment. Fig. 5 is a side elevation of artof the skate and so1e-plate inverted an a longitudinal sectionof theclamp-controlling attachment of Fig. 3. Fig. 6 is a detail ofthecontrolling device of Fig. 4' in side elevation.

- A represents the runner of the skate, b the heel-plate, and c thesole-plate, said sole and heel plates being fixedly attached to therunner in the usual manner. The heel-clips o are carried on the jaws b,which are pivoted together at 7', and the toe-clips e are carried on thejaws f, which are pivoted together at g and suspended under plate a bythe heads of the studs h, inserted through curved slots 0'," of the jawsand fixedly set in the under side of the sole-plate, so as to open andclose the clips to some extent for gripping and releasing the soleaccordin as the aws are shifted forward or backwar on the studs h. The

usual heel-cli d bein part of the heel-plate fixedly attached to t erunner is also em p'loyed to engage the front of the heel. The pivot gcarries the usual stud g, projecting below the jaws,in which theclamp-adjusting screw i works, said screw also working in a stud jpendent from lever s behind the pivotrivet j, by which it is fulcrumedon the forward end of the heel-clamps b.

In one form of my attachment I provide a suitable shoulder at k in therearstandard Z, to which the sole-plate c is attached, and apply a yokem with an adjusting-screw n bearing on said shoulder 7c and with its bow0 engaging stud g The adjustin screw nis provided with a check-nut p, wch is to be so set that when the end of the screw draws against shoulderk bythe action of lever s cllps 6 will grip the sole of the shoesufficiently tight and then further clamping movement will be arrestedand thereafter the rest of the draw by the lever s will be expended onthe clips d and d, which owing to the greater stifiness of the heel ofthe shoe will not grip the foot of the wearer uncomfortably. In

this case the collarg for turning the adjustingscrew ft is fixedlyattached to the screw; but in Fig. 1" I show that by dispensing with theyoke m and applying check-nuts r and r on the screw, said screw beinthreaded through the nuts, and providing t e shoulders s on the upperedge of the skate runner, this shoulder and the nuts when adjustedproperly and checked against each other serve the same purpose ofarresting the draw on the clips e at the proper time and thereafterexpending the action of the levers on the heelclips (1 and d By anotherplan an adjustable wedge 25, Figs. 3 and 5, may be laced between thejaws f under the sole-p ate 0 to limit their clampingaction, said platebeing set and held in position by a clamp-screw '11,. The,

tion except as herein described.

IIO

It will be seen that various contrivances toe and heel clamps and acommon 0 erating device therefor, of a yoke connecte to said toe-clampsand movable therewith, and an adjusting stop-screw carried by said yokeand arranged to coact with a fixed portion of the skate.
